Seems acceptable. Though settings-wise it would seem that returning from the DR would be something that'd take much time and effort and as such, exploitation of such spells would be of little impact (not saying they should be easy to have, just pointing my impressions of the settings).
Oh, psst, I'd also like to say it's a bit unfair to have the curse in-game when falling off of the end of the world, getting stuck in places where only /die is the solution, etc, still make it so that people end up there without having any true reason to be. Yet, I agree, those are quite rare these days, compared to what it was.
